Hi all,I am using STM32F042 series mcu, and IAR as compiler.I have some #define statements in main.h which provides some setting configurations. Forexample we have different custom pcbs which have either active low or active high button. If I place #...

Hello everyone,For one of our commercial product we are using STM32F0 as mcu, and IAR as compiler. Since the device is battery powered, it sleeps for 1 sec then wakes up and does some adc measurements and sleeps for next 1 sec. Instead of doing measu...

Hi Everyone, When I send a structure pointer as an agument to a function, and trying to catch address of a variable in the structure in the function, MCU goes in to hardfault handler function. Let me simplify the problem as below,uint8_t *ptr1;uint3...

Just to check if problem is related to RTC, I commented out MX_RTC_Init() and problem seems to be solved. Now I will try what you recommended.

Hi clive1, Thanks for your reply, You may be right since we use sleep mode with regulator in normal mode. I will try to diassemble the code and examine, however I have confused about working for hours(waking up every 100ms with RTC, can request, bu...

Thanks for your answer,I don't think there is a issue related to stack overflow. SP initial address is 0x20000F50 and min value of stack pointer while code is running is 0x20000E00 and Stack size is 0x600.I will share content of vector tables placed ...

This is the first time I heard about it. Thanks for the link. The only point confused me is the situation below,Instead of declaring the array inside the strucure, I decleared as a global variable without structure. With this way it worked without an...

@TDK Thanks for your answer.I am not trying to devide 0xAA by 4.Let say my array is like that;sensor.Data[0] = 0xAA;sensor.Data[1] = 0xAB;sensor.Data[2] = 0xAC;sensor.Data[3] = 0xAD;And I have a function;void foo(uint32_t info){}I want to call this ...
